if identical in shape the H code will always be worth more. that being said the original slant/318 car will be worth more then it would be all original..
I believe it does because I understand his original question to be does a tribute car value the same as an original h code car.
I agree in most cases an upgrade to a higher horsepower motor in any car would bring more money to a point, and where is that tipping point?
I just parted out a totally rusted and clapped out 68 dart gt with a /6. the front frame rails were rusted in 2. it was either a H high price class car or P premium price class car, lots of options. back when it was new it was a real pretty car. I believe that car would be worth the most value if it COULD HAVE BEEN restored in its stock form.
